Delayed crosslinking polycondensable composition, use thereof for producing coatings and resulting coatings

摘要

The invention concerns a polycondensable composition capable of being used in coatings with delayed crosslinking, in particular at room temperature. The invention aims at providing a composition comprising: a) an additive composition between an aliphatic isocyanate and a nitrogenous five-membered heterocycle of aromatic type having a nitrogen-carbon-nitrogen sequence of the type -N(H)-C(-)-N-; b) at least one polyol, said heterocycle being substituted by at least one hydrocarbon chain having 1 to 10 carbon atoms. The invention is applicable to the coating industry.
